Story: As a Quay administrator I like to be able to forward all logs to a Splunk deployment so that I can do for further analysis and offload the internal database.

Why is this important: Quay supports ElasticSearch as a log forward target. Splunk is another stream/log data analysis solution common in enterprise deployments and usually deployed as an alternative to ElasticSearch rather than in parallel.

Acceptance criteria:

• all logs relevant for audits are forwarded to Splunk Enterprise
• no additional plugins are required to be installed on the Splunk side
• SSL communication with Splunk
• Token-based auth with Splunk
